  • a secondary power generation facility 5 such as a hydrogen gas turbine power plant is installed in the vicinity of the regional power grid 6 in a specific residential area, and is directly transported from the above-mentioned secondary hydrogen storage facility 4 or primary hydrogen storage facility 3 by a trailer 7 or the like. Secondary power generation is performed using the generated hydrogen, and the electricity generated by this secondary power generation is supplied to the regional power grid 6.
  • a secondary power generation device 8 such as a hydrogen fuel engine or a hydrogen fuel cell is installed in each household in a specific residential area to generate electric power of the regional power grid 6. Can be used separately or in combination.
